获取给定日期的日期以排除两个日期之间的差额

Question

I want to exclude sunday from the differences between two dates. I have used the following code to get the differences between two dates:

leaveDuration  = (int)( (leavetodate.getTime() - leavefromdate.getTime()) / (1000 * 60 * 60 * 24) );

Now I want toexclude sunday between the two dates. Or for that matter I want to exclude a holiday in general. How should the above code be modified to get the desired result?

You need to use Calendar

int getDiff(Date fromDate, Date toDate) {
    Calendar c = Calendar.getInstance();
    c.setTime(fromDate);
    int workDays = 0;
    while (c.getTime().before(toDate)) {
        if (c.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {
            workDays++;
        }
        c.add(Calendar.DATE, 1);
    }
    return workDays;
}
